How to get Premium templates and the Seasonal look
On a paid plan, add the Premium add-on ($5 a month or $50 a year) under Billing, or click Unlock on a premium template; then use any premium template and turn on the Seasonal look in Branding.
Premium unlocks every premium template, including new ones as they launch, and the Seasonal look on any template: a seasonal tint, home-page photo and headline that follow spring, summer, fall and winter.
